9. Write a program using Atom and submit via Blackboard.

a. Request an integer whole dollar amount from the console.

b. Using the least amount of bills ($50,$20,$10,$5,$1) necessary, calculate how many of each bill type you will need to get to that value.

Output Example 1 (input is bold and italicized)

Enter a whole dollar amount as n integer: 633                                                           

You will need:

12   $50 bill(s).

1   $20 bill(s).

1 $10 bill(s).

0   $5 bills(s).

3    $1 bill(s).

Output Example 2 (input is bold and italicized)

Enter a whole dollar amount as an integer: 364                                                        

You will need:

7     $50 bill(s).

0     $20 bill(s).

1   $1 bill(s).

0     $5 bills(s).

4     $1 bills(s).

2/4 Purchase 1,000 16

2/20   Sale 1,500 30

4/2 Purchase 1,000 20

Compute the ending inventory, assuming Ehlo uses:

(a) Perpetual system, FIFO cost flow.

(b) Periodic system, LIFO cost flow.

(c) Perpetual system, LIFO cost flow.

(d) Periodic system, weighted-average cost flow.

(e) Perpetual system, moving-average cost flow.

I'm a stock trader. I entered and exited the market so far 3 times this year.

1) entered on 12/31/19 at 86.5 and exited on 1/27/20 at 92.72 for a gain of 7.1%.

2) re-entered on 2/5/20 at 105.82 and exited on 2/20/20 at 114.66 for a gain of 8.4%.

3) re-entered on 4/15/20 at 61.55 and exited on 4/30/20 at 69.77 for a gain of 13.4%.

What is the total return to date (should be around 40% to 50%) and a simple formula how to calculate it. I need to do this on many different time frames.

Please make it easy to understand.

Suppose we are writing a C++ program for the sales department of a small company. The department has 4 sales person and is selling 5 products. The program will allow the input of each sale made (sales person, product, sales amount). The program will also allow a user to see the sales made by a particular sales person or the sales on a particular product.

Requirement of the Program:

1. Using a 2-D array as a data structure for storing the sales information

2. Containing a menu that allows a user to

1. Enter a sale
2. Check the sales made by a sales person
3. Check the sales on a product
4. Exit the program

Here is a sample run of the program:
